GLOSSARY

The short-form creator glossary

109 terms every TikTok, Reels, and Shorts creator hears constantly — defined in plain English, with why each one matters for your reach.

Affiliate marketing

Affiliate marketing is promoting another company's product with a unique link or code and earning a commission on the sales you drive. For short-form creators it turns content into performance-based income: you get paid per conversion rather than per post, so a single evergreen video can keep earning long after you publish it.

Algorithm signal

An algorithm signal is any measurable viewer behavior — watch time, completion, rewatches, likes, comments, shares, saves, follows, or 'not interested' taps — that a short-form platform's recommendation system uses to decide how widely to distribute a video. Stronger positive signals from early viewers generally earn a video more reach.

Appeal

An appeal is a request asking a platform to re-review a moderation decision — a removed video, a strike, or a restriction — that you believe was made in error. On TikTok, Instagram, and YouTube, submitting an appeal sends the case back for another look, and a successful one can restore your video and reverse the associated penalty.

Aspect ratio

Aspect ratio is the width-to-height proportion of your video frame, written as width:height. Short-form platforms are built for the vertical 9:16 ratio that fills a phone screen, so filming and exporting vertically is essential. A square or horizontal video leaves black bars or gets cropped, wasting screen space and attention.

Audience retention

Audience retention is the share of a video's length the average viewer actually watches, shown as a curve that tracks how many people are still watching at each second. On short-form platforms it's the clearest read on whether your pacing holds attention, and it drives how far a video spreads.

Average view duration

Average view duration is the mean amount of time viewers spend watching your video, calculated as total watch time divided by total views. On short-form platforms it's often shown as a percentage of video length, and it's the clearest single readout of how well your video holds attention.

B-roll

B-roll is supplemental footage layered over or between a video's main content—shots of your workspace, product, hands, surroundings, or process—used to add visual variety while a voiceover or main clip carries the message. In short-form video, b-roll keeps the screen changing so viewers have a reason to keep watching.

Batch filming

Batch filming is recording several videos back-to-back in one session instead of one at a time. For solo creators it's the core efficiency move: set up lighting and mindset once, then bank a week or a month of content in one block, protecting a consistent posting schedule against busy days.

Brand deal

A brand deal is a paid agreement where a company pays you to feature its product or service in your short-form content. Terms cover deliverables, usage rights, exclusivity, and pay, and rates depend on your audience, niche, and the scope of work. It's usually the highest-value income stream a mid-size creator can build.

Call to action (CTA)

A call to action (CTA) is a direct prompt in a short-form video or caption asking viewers to do something specific—follow, comment, share, save, or watch another video. CTAs convert passive viewers into engaged ones, turning watch time into signals like comments and shares that platforms use when deciding distribution.

Caption

A caption is the text you write to accompany a short-form video, shown below or beside the post. Beyond describing the clip, it does real work: it can extend a hook, prompt comments, feed keywords to search, and give viewers a reason to rewatch, all in the one or two lines people actually read.

Carousel

A carousel is a multi-image post that viewers swipe through horizontally, available on TikTok as photo posts or slideshows and on Instagram as multi-slide posts that can mix photos and video. Each swipe is an engagement signal, and carousels often earn strong saves and shares, making them a low-effort complement to video.

Coins

Coins are TikTok's virtual currency that viewers buy with real money and spend on gifts during LIVE broadcasts and, in some regions, on videos. For creators, Coins are the input side of tipping: when a viewer converts Coins into a gift you receive, it becomes Diamonds you can redeem. Prices vary by region — check TikTok's official pages.

Cold open

A cold open is a video that drops the viewer straight into the action or the payoff with no intro, setup, or self-introduction. In short-form video, where the first second decides whether someone stays or swipes, a cold open uses those opening moments to hook attention instead of spending them on a greeting.

Comment bait

Comment bait is any deliberate element in a video designed to provoke comments — a small intentional mistake, a divisive take, an unanswered question, or an on-screen prompt. Because comments are an engagement signal to recommendation algorithms, creators use comment bait to improve distribution, though heavy-handed engagement bait can annoy viewers and some platforms demote it.

Commission

Commission is the percentage of a sale you earn when someone buys a product through your affiliate link, code, or TikTok Shop tag. Instead of a flat fee, you're paid a cut of each order your content drives, so your income scales directly with how much you actually sell rather than how many views you get.

Community guidelines

Community guidelines are the platform's published rules for what content is allowed, covering things like safety, harassment, misinformation, and restricted topics. On TikTok, Instagram, and YouTube, violating them can get a video removed, limit its reach, or lead to account penalties, so knowing the current rules protects both your posts and your account.

Completion rate

Completion rate is the percentage of viewers who watch your short-form video all the way to the end. Platforms like TikTok, Instagram Reels, and YouTube Shorts treat it as a core signal of video quality, so a higher completion rate generally means your video gets shown to more people.

Content bucket

A content bucket is a recurring theme or category you post within, so your account covers a few defined topics instead of random one-offs. Most short-form creators run three to five buckets, like tutorials, behind-the-scenes, and hot takes, rotating between them to stay consistent without burning out on ideas.

Content pillar

A content pillar is one of the three to five recurring themes a creator rotates through so every video fits their niche while staying varied. A fitness creator might rotate workout tutorials, meal prep, and mindset videos. Pillars keep a posting schedule sustainable and make your account legible to both viewers and the algorithm.

Cover photo

A cover photo is the still frame that represents your video on your profile grid and in search, chosen either from a frame of the video or an uploaded image. It's the thumbnail a browsing viewer judges before tapping, so a clear, readable cover can pull in views long after a video first posts.

CPM

CPM, or cost per mille, is the price an advertiser pays for one thousand ad impressions, and it's the standard unit for buying and comparing ad campaigns. For creators, CPM is the benchmark brands use to value paid placements, so understanding it helps you sanity-check what a sponsored post or ad-driven deal is actually worth.

Creativity Program

The Creativity Program is TikTok's payout program that rewards eligible creators for longer, original videos — generally those over one minute — based on qualifying views and engagement. It replaced the older Creator Fund in many regions and has itself been rebranded as Creator Rewards; rates vary by market, so check TikTok's official pages.

Creator Fund

The Creator Fund was TikTok's original payout program that paid eligible creators a share of a fixed pool based on qualifying video views. TikTok has largely replaced it with the Creativity Program, now Creator Rewards, in many regions, and payout rates always varied — check TikTok's official pages for what's available where you are.

Creator Rewards Program

The Creator Rewards Program is TikTok's monetization program that pays eligible creators for qualified views on original videos longer than one minute, with payouts shaped by factors like watch time, engagement, and search value. It replaced TikTok's earlier Creator Fund era. Eligibility requirements change, so confirm current thresholds on TikTok's official pages.

Diamonds

Diamonds are the reward units TikTok credits to your account when viewers send you gifts during a LIVE. Gifts bought with Coins convert into Diamonds at TikTok's own rate, and once you meet the threshold you can redeem Diamonds for real cash. Conversion rates and payout minimums vary by region — check TikTok's official pages.

Duet

A Duet is a TikTok feature that places your video side by side with another creator's original video so both play simultaneously in a split screen. Creators use Duets to react, harmonize, or add commentary in real time, and the original creator is credited automatically with a link back to their video.

Duet chain

A duet chain is a series of duets where creators keep adding their own panel alongside a video, each response building on the last. On TikTok it turns one clip into a growing collaborative thread, letting you borrow an existing video's momentum and put your reaction, harmony, or twist in front of its audience.

Engagement

Engagement is the sum of active interactions on your video — likes, comments, shares, and saves — usually measured against views as a rate. On short-form platforms these actions signal to the recommendation system that a video is worth surfacing, with shares and saves generally read as stronger intent than a like.

Engagement rate

Engagement rate is the percentage of viewers who interact with your video — likes, comments, shares, saves, and follows — relative to its views or reach. It tells platforms that a video sparked a reaction beyond passive watching, and it's a standard benchmark for comparing performance across videos and accounts.

Evergreen content

Evergreen content is a video whose topic stays relevant and searchable for months or years — tutorials, how-tos, explainers, and recommendation lists — rather than tying itself to a trend or news moment. Evergreen videos can keep collecting views through search and recommendations long after posting, while trend-based content usually spikes and fades quickly.

Faceless account

A faceless account is a social media account that publishes videos without showing the creator's face or identity, using voiceovers, text overlays, b-roll, screen recordings, or AI narration instead. Faceless channels are popular with creators who want privacy, want to scale multiple accounts, or feel more comfortable off camera.

Following feed

The following feed is the tab that shows videos only from accounts a viewer already follows, separate from the algorithmic For You feed. On TikTok it sits at the top of the app, and it's where your most loyal viewers see your posts without the algorithm deciding whether to serve them.

FYP (For You page)

The For You page (FYP) is TikTok's algorithmically personalized home feed, where the platform serves each user videos it predicts they'll watch and engage with — mostly from accounts they don't follow. Landing on the FYP is how short-form videos reach new audiences, since recommendation, not follower count, drives most TikTok views.

Gifting

Gifting is the act of viewers sending you virtual gifts — bought with Coins — to support you, most commonly during a TikTok LIVE. Each gift converts into Diamonds in your account that redeem for cash, making gifting a direct viewer-to-creator tipping mechanism. Eligibility, gift values, and payout rates vary by region — check TikTok's official pages.

GMV

GMV, or gross merchandise value, is the total sales value of products sold through your content over a period, before fees, refunds, or returns are deducted. On TikTok Shop it's the headline number for affiliate and shop performance, measuring what your videos and lives drove in sales — not what you personally earned.

Green screen

Green screen is an effect—built into TikTok, Instagram Reels, and CapCut—that replaces a video's background with an image, screenshot, video, or webpage, letting a creator appear in front of any visual while talking. It's the standard format for reacting to headlines, screenshots, and other on-screen content.

Hook

A hook is the opening moment of a short-form video—usually the first one to three seconds—designed to stop viewers from scrolling and commit them to watching. It can be a spoken line, on-screen text, a visual, or a bold claim, and it largely determines whether the rest of the video gets seen.

Hook rate

Hook rate is the percentage of viewers who keep watching past the first few seconds of your video instead of swiping away immediately. It measures how well your opening earns attention, and because those first seconds gate everything after them, hook rate is one of the strongest early predictors of how far a video travels.

Impressions

Impressions are the total number of times your video was shown on screen, including repeat views by the same account and appearances in feeds, search, and profile visits. Comparing impressions to reach tells you how often the platform re-served your content and whether viewers came back for more.

Initial test batch

An initial test batch is the small first wave of viewers a platform's algorithm shows a new video to in order to measure how it performs before deciding whether to push it further. Strong completion and engagement in this window typically earn wider distribution; weak signals usually stall the video early. TikTok doesn't publish batch sizes.

Jump cut

A jump cut is an abrupt edit that removes the pause between two moments of the same shot, making the speaker or scene visibly skip forward. In short-form video, jump cuts strip out dead air so every second carries information, keeping pacing tight enough for viewers to stay through the video.

Keyword

A keyword is a word or phrase your target viewers type into search or expect to hear on a topic, which you place in your video so platforms can match it to those searches. On short-form, keywords live in your spoken audio, on-screen text, and caption — and choosing the right one decides which searches you can rank for.

LIVE gifts

LIVE gifts are virtual items viewers send you during a TikTok LIVE broadcast as a form of tipping. Viewers buy Coins with real money, spend them on animated gifts, and those gifts convert into Diamonds in your account that you can redeem for cash. Values and eligibility vary by region — check TikTok's official pages.

Loop

A loop is a short-form video edited so its ending flows seamlessly back into its beginning, encouraging viewers to watch it more than once—often without realizing it restarted. Loops lift rewatch rate and total watch time, two signals widely believed to help videos perform in recommendation feeds.

Match cut

A match cut is an edit where a shape, movement, or composition in one shot lines up with the next, so the transition feels seamless and intentional. In short-form video, match cuts hide the seam between clips, keeping pacing smooth and giving edits a polished, satisfying rhythm that holds attention.

Media kit

A media kit is a short document creators send to brands that summarizes who you are, your audience, and your best performance numbers to win paid partnerships. It typically fits on one or two pages and includes your niche, follower counts across platforms, average views and engagement, past collaborations, and your contact details or rates.

Montage

A montage is a sequence of short clips edited together, usually set to music, that compresses a process, a story, or a span of time into a fast-moving series of shots. In short-form video, montages pack a lot of visual change into a few seconds, keeping the screen alive so viewers stay through to the end.

Net followers

Net followers is your follower gain minus your follower loss over a set period. On short-form platforms it's the honest read on real growth, because a video can rack up gross follows while quietly shedding people who unfollow after watching — the net number is what actually moves your audience up or down.

Niche

A niche is the specific topic, audience, or content category a creator consistently posts about, like budget cooking, watch restoration, or ADHD productivity. On short-form platforms, a clear niche helps the recommendation algorithm learn who your videos are for, so it can push them to viewers most likely to watch and follow.

On-screen text

On-screen text is the words you overlay directly on the video itself, distinct from the caption below it. In short-form it carries the hook, labels what's happening, and keeps viewers who watch on mute reading along, which is most of them, making it one of the highest-impact edits you can add.

Open loop

An open loop is an unanswered question or unresolved tension you plant early in a video to make viewers stay for the answer. By opening a curiosity gap in the first seconds and only closing it later, you give people a concrete reason to watch past the opening instead of swiping away.

Original sound

Original sound is audio you create and post with your own video — your voice, music, or any recording — rather than a track pulled from the platform's library. On TikTok it's credited to your account and gets its own sound page, so if others use it, every video links back to you as the source.

Pacing

Pacing is the speed and rhythm at which information, cuts, and visual changes move through your video. In short-form, tight pacing, meaning quick cuts, no dead air, and a new beat every few seconds, keeps the viewer's thumb still, while slow or uneven pacing invites the swipe long before your point lands.

Payoff

A payoff is the moment a video delivers on the promise its hook made: the answer, punchline, result, or reveal viewers stayed to see. In short-form, a satisfying payoff is what turns a watch into a like, a share, or a rewatch, and a weak one wastes the attention your hook earned.

Pinned comment

A pinned comment is a comment the creator fixes to the top of a video's comment section so it stays visible above all others. On TikTok, Reels, and Shorts, creators use it to add context, answer a repeated question, drop a call to action, or seed a conversation that lifts the video's engagement.

Pinned video

A pinned video is a post you fix to the top row of your profile grid so it shows first regardless of when you published it. TikTok, Instagram Reels, and YouTube Shorts let you pin up to three, making them the default introduction every profile visitor sees before your newer uploads.

Playlist

A playlist is a creator-made collection that groups related videos on your profile into an ordered, named set viewers can watch back to back. On TikTok and YouTube Shorts, playlists organize your content by topic or series, help viewers binge a theme, and surface older videos that would otherwise sink down your grid.

Positioning

Positioning is the distinct space your account occupies in a viewer's mind — the specific angle, personality, or promise that makes you recognizably different from other creators covering the same topic. On short-form platforms, strong positioning is why someone follows you instead of the dozens of similar accounts on their feed.

Posting cadence

Posting cadence is how often and how regularly you publish — for example, three videos a week at consistent times. On short-form platforms a steady cadence gives the algorithm more chances to find a winner and trains your audience to expect you, though consistency you can sustain matters more than raw volume.

POV

POV (point of view) is a short-form video format that puts the viewer inside a scenario, either literally—filmed as if through their eyes—or as a labeled premise like "POV: you're the last one to find out." The label instantly frames the video as a relatable situation viewers project themselves into.

Predicted reach

Predicted reach is an AI-generated estimate of how many viewers a video could get, calculated before posting by analyzing the video's hook, retention structure, and packaging. The concept was popularized by pre-post analysis tools like ReelTok. It's a directional estimate for comparing drafts, not a promise of actual views once the video is live.

Profile views

Profile views is the number of times people opened your profile page over a given period. On short-form platforms it's a curiosity signal — a viewer liked a video enough to see who made it — and a leading indicator of follows, since most people check your profile before deciding to follow.

Q&A feature

The Q&A feature is a built-in TikTok tool that lets viewers submit questions on your profile or during a live, which you can then answer in a dedicated video or reply. It turns your comment section into a structured prompt bank, giving you an endless supply of audience-sourced content ideas.

Rate card

A rate card is a creator's ready-to-share list of prices for the deliverables brands buy — a sponsored video, a set of posts, a story, usage rights, or exclusivity. It sets your baseline so you quote consistently instead of guessing per deal, and it signals to brands that you price your work professionally.

Reach

Reach is the number of unique accounts that saw your video at least once, counting each viewer one time no matter how often they watched. It measures the true size of your audience for a post, distinct from impressions and views, which can count the same person repeatedly.

Reach rate

Reach rate is the percentage of your followers, or of a defined audience, that a given video actually reaches. On short-form platforms it reveals how much of your base the algorithm chose to serve — a low reach rate is normal on recommendation feeds, where most followers never see any single post.

Repost

A Repost is TikTok's one-tap share feature that recommends someone else's video to your followers and friends in their For You feeds, similar to a retweet without a quote. Reposted videos don't join your main profile grid; they surface in feeds with a label showing you recommended them, and each repost acts as a share signal for the original video.

Retention graph

A retention graph is the analytics chart showing what percentage of viewers are still watching at each second of your video. It's the clearest diagnostic short-form platforms give you: every dip marks a moment people left, and the shape of the curve tells you exactly where your edit is losing attention.

Rewatch rate

Rewatch rate is the percentage of viewers who watch your video more than once, whether by letting it loop or scrolling back to it. On short-form platforms a rewatch pushes average view duration past 100 percent of the video's length, which reads as an unusually strong quality signal.

RPM

RPM, or revenue per mille, is how much money you actually earn per thousand views after the platform's share and deductions — your real take-home rate. Unlike CPM, which is what advertisers pay, RPM is what lands in your pocket, making it the truer measure of how well your views convert into income.

Safe zone

The safe zone is the central area of your vertical frame that stays clear of the platform's interface, meaning the caption, username, buttons, and progress bar that overlay the edges. Keeping important visuals and text inside the safe zone ensures nothing critical gets hidden behind TikTok, Reels, or Shorts UI.

Save rate

Save rate is the percentage of viewers who bookmark your video to watch again later using the save or favorite button. Saves signal lasting usefulness — viewers plan to return — which is why how-to, recipe, and tutorial content with high save rates often keeps getting distributed long after posting.

Search results

Search results are the videos a platform surfaces when a viewer types a query into its search bar, ranked by how well each video matches the words in that search. On TikTok, Reels, and Shorts, search has become a real discovery surface, so ranking for the right queries can send you views for months after posting.

Series

A series is a set of videos built around one recurring theme, format, or storyline, released as numbered or clearly linked installments viewers can follow. On short-form platforms, a series turns one-time viewers into return visitors by giving them a reason to come back for the next part.

Session time

Session time is how long a viewer stays inside the app during the visit that includes your video — counting everything they watch, not just your clip. Short-form platforms optimize for keeping users in-app, so content that leads viewers to keep scrolling or watch more can earn extra favor beyond its own metrics.

Shadowban

A shadowban is an unannounced drop in a creator's distribution, where a platform quietly limits how often their videos appear in recommendations without notifying the account. It's not an official TikTok term — creators use it to describe sudden reach drops that may stem from guideline flags, repeated violations, or ordinary algorithm variance.

Share rate

Share rate is the percentage of viewers who send your video to someone else or repost it to their own audience. Many creators treat it as the strongest engagement signal on short-form platforms because a share puts your video in front of people the algorithm hadn't reached yet.

Sound page

A sound page is the dedicated feed that collects every video using a specific audio track or original sound. On TikTok, tapping the spinning record at the bottom of a video opens it, showing how many videos use that sound and letting viewers scroll through them all — which makes trending sounds a discovery path in their own right.

Spark Ads

Spark Ads are a TikTok ad format that turns an existing organic post — yours or a creator's — into a paid ad while keeping the original video's likes, comments, and the creator's handle. Unlike a standard ad, engagement accrues to the real post, so a Spark Ad looks native and builds on organic proof.

Speed ramp

A speed ramp is an edit that smoothly changes a clip's playback speed mid-shot, slowing down for emphasis then speeding up to skip ahead, rather than cutting between fixed speeds. In short-form video, speed ramps add rhythm and drama, guiding the viewer's eye to the moment that matters and compressing the parts that don't.

Sponsorship

A sponsorship is an ongoing or recurring paid partnership where a brand supports you over time — across multiple posts or a set period — in exchange for regular promotion. It's a longer commitment than a one-off brand deal, often with exclusivity in your niche, and terms and rates vary with your reach, engagement, and deliverables.

Stitch

A Stitch is a TikTok feature that lets you clip up to five seconds of someone else's video and use it as the opening of your own, so your response plays right after their clip. It's built for reply-style content — answering questions, correcting takes, or continuing a story — with automatic credit to the original creator.

Stitch reply

A stitch reply is a video that clips a few seconds of someone else's post and then cuts to your own response. On TikTok, stitching lets you answer a question, react to a claim, or continue a story using the original as your setup, borrowing its context to launch straight into your own take.

Storytime

Storytime is a short-form video format where a creator recounts a personal story or dramatic experience directly to camera, often over b-roll or gameplay footage, and frequently split into parts. The format runs on narrative tension—viewers stay to hear how it ends, which keeps watch time high.

Strike

A strike is a penalty a platform records against your account when a video violates its community guidelines. Strikes accumulate, and enough of them within a period can restrict features, limit reach, or lead to account suspension. On TikTok they're tracked in your account's safety or account-status section so you can see your standing.

Sub-niche

A sub-niche is a narrow, specific segment within a broader content category — for example, cast-iron cooking inside the wider food niche. On short-form platforms, choosing a sub-niche sharpens who your videos are for, making it easier for the algorithm to find your ideal viewers and for those viewers to see you as the account for their exact interest.

Swipe-away rate

Swipe-away rate is the percentage of viewers who scroll past your video quickly, usually in the first seconds, without watching a meaningful portion. It's the inverse of hook rate — a high swipe-away rate means your opening is losing people fast, and it's one of the clearest signals that a video's start needs fixing.

Target audience

Your target audience is the specific group of people your content is made to reach and serve — defined by their interests, problems, and what they already watch. On short-form platforms, knowing your target audience shapes every hook, topic, and reference so the algorithm can match your videos to the viewers most likely to engage.

Text overlay

Text overlay is on-screen text added to a short-form video that viewers read while watching, used for hooks, captions, context, or emphasis. Because many viewers scroll with sound off or half-listening, overlay text lets a video communicate its point visually and hold attention without relying on audio alone.

Text-to-speech (TTS)

Text-to-speech (TTS) is a feature that reads typed text aloud in a synthetic voice, letting you add narration to a video without recording your own. On TikTok, Instagram, and editors like CapCut, creators use TTS to voice captions, deliver lines hands-free, and keep faceless videos moving with audio.

Thumbnail / cover

A cover, or thumbnail, is the still frame and text that represents your video on your profile grid, in search, and on platform feeds. On short-form, it's what makes someone tap into a video from your profile or a topic page, so a clear, legible cover directly affects how much of your back catalog gets watched.

TikTok Promote

TikTok Promote is TikTok's built-in paid boost feature that lets creators pay to push an existing video to a wider audience, choosing goals like more views, followers, or website visits. It's an ad product, so promoted views arrive labeled as sponsored and don't behave like organic For You page distribution.

TikTok SEO

TikTok SEO is the practice of optimizing your videos to rank in TikTok's search results for specific queries people type. It works like search engine optimization for video: you put the words viewers search into your spoken audio, on-screen text, caption, and hashtags so the platform can match your content to those searches.

TikTok Shop

TikTok Shop is TikTok's built-in e-commerce feature that lets viewers buy products without leaving the app, through in-video links, LIVE shopping, and a shop tab. Creators earn commissions by tagging products in their content or by selling their own, making it a direct path from a video to a checkout. Availability and rates vary by region.

TikTok Studio

TikTok Studio is TikTok's free creator dashboard — available in-app and on desktop — that combines analytics, upload and scheduling tools, monetization tracking, and account health checks in one place. Creators use it to read metrics like watch time, completion rate, and traffic sources, and to see whether any content was flagged for guideline issues.

Traffic source

Traffic source is the breakdown of where a video's views came from — the For You feed, profile, search, sounds, or the following feed. On short-form platforms it tells you which distribution channel is actually working, so you can build on what's pulling views instead of guessing.

Transition

A transition is the visual technique that moves a video from one shot to the next, whether a cut, swipe, spin, zoom, or outfit change timed to the beat. In short-form video, transitions keep the screen changing and give edits a satisfying rhythm, which holds attention and can earn rewatches when the move is clean.

Trend cycle

A trend cycle is the lifespan of a sound, format, or challenge — from early adoption, through peak saturation, to decline. On short-form platforms, catching a trend on the way up gives you outsized reach, while joining after saturation buries your video under thousands of near-identical takes.

Trending audio

Trending audio is a sound, song clip, or voiceover currently being used in a rising number of videos on TikTok or Instagram Reels, identifiable by an arrow or trending label in the audio library. Using one attaches your video to an audio page and a format viewers already recognize.

UGC (user-generated content)

UGC, or user-generated content, is brand-focused content made by everyday creators rather than the brand itself, most commonly short videos showing a product in an authentic, personal style. In 2026, UGC is also a paid creator business model: brands pay creators to produce ad-style videos for the brand's own channels, no follower count required.

Usage rights

Usage rights are the terms that define how, where, and for how long a brand can use content you created — for example on their own channels, in paid ads, or on billboards. In creator deals they're a separate value from making the video: broader, longer, or paid-ad usage costs more, because you're licensing your work beyond your own feed.

View-to-follower ratio

View-to-follower ratio is the number of views a video gets divided by your follower count, showing how far past your existing audience it traveled. A ratio above one means the platform pushed the video to non-followers, which on TikTok and Reels is where most viral growth comes from.

Viral coefficient

Viral coefficient is how many new viewers each existing viewer brings in — through shares, duets, stitches, or word of mouth. On short-form platforms, a coefficient above one means a video keeps spreading on its own, because every wave of viewers recruits more people than the wave before it.

Virality score

A virality score is a 0-100 rating that estimates how likely a short-form video is to perform well before you post it, generated by AI tools that analyze the hook, pacing, visuals, and caption. Popularized by pre-post analysis apps like ReelTok, it's a prediction meant to guide edits, not a guarantee of views.

Voiceover

A voiceover is a recorded narration laid over your video's visuals, carrying the script while b-roll, screen recordings, or footage play underneath. In short-form video, voiceover lets you separate what viewers hear from what they see, so you can write a tight script and pair it with whatever footage keeps the screen moving.

Watch time

Watch time is the total amount of time viewers spend watching your video, summed across all views and rewatches. Short-form platforms use it alongside completion rate to judge how well a video holds attention, and accumulating watch time quickly after posting helps a video earn wider distribution.

Watermark

A watermark is a logo, username, or platform stamp overlaid on a video, like the moving TikTok logo added to downloaded TikToks. Watermarks matter for creators because reposting a watermarked video to another platform can hurt distribution — Instagram has said it makes Reels with visible watermarks less discoverable.

Whitelisting

Whitelisting is when a creator grants a brand permission to run ads through the creator's own social handle, so the brand's paid promotions appear to come from the creator's account. On TikTok this is enabled through Spark Ads authorization; the creator stays the visible face while the brand controls targeting and budget.
